It's true. He said he was withdrawing because of a sore back and will join Dustin Johnson, Retief Goosen, Jim Furyk and Ian Poulter as early withdrawals from the tournament.

Singh was cleared on Tuesday by PGA Tour commissioner Tim Finchem of any wrongdoing even though it was previously thought he might be suspended because of his use of IGF-1, which is a substance found in deer antler spray.

Here's what the AP said about Singh:

"He declined to comment to a PGA Tour media official Tuesday after the tour dropped his case on the anti-doping violation. Singh has not spoken to reporters since he released a statement in late January that said he was shocked to learn the deer antler spray he had been taking might contain IGF-1, which is on the banned list."
